Hi @Kader Saheb
Thank you for posting your issue on Microsoft Q&A.

I understand that you cannot login to test tenant to delete registered domain and cannot use the Microsoft Authenticator App because the account doesn't exist anymore.

Global administrators have capabilities to re-register MFA. Contact Your Global Administrator and ask them to Re-register MFA for you. When you sign in again, you will be prompted to set up your MFA. Follow the prompts to add the Microsoft Authenticator app again and sign in account you will receive code.

If you are the only global admin on the account and are blocked entirely, you can reach out to our support team. You can look into below article to get support numbers depending on your country.

 or creating a ticket through a different account:   https://learn.microsoft.com/en-us/microsoft-365/admin/get-help-support?view=o365-worldwide#online-support

While creating a ticket with Microsoft support team. Give them the tenant ID which is locked out in your description. Tell them that no admin account has access anymore and your partners also have no access anymore.

Hope this helps. Do let us know if you have any further queries.
